Results of tricuspid valve reconstruction using a semirigid ring or a flexible band
Journal of Cardiothoracic Surgery volume 10, Article number: A317 (2015)
Current concepts for tricuspid valve surgery recommend concomitant tricuspid valve reconstruction (TVR) utilizing annuloplasty devices over simple suture annuloplasty.
It is unclear if flexible bands offer the same long-term results like rigid or semi-rigid rings. We aimed to evaluate possible outcome differences between the flexible SJM Tailor Band (FB group) and the Carpentier-Edwards rigid MC3-Ring (RR group).
We retrospectively evaluated 141 patients undergoing tricuspid valve reconstruction (TVR) with the MC3-ring or the Tailor Band or suture annuloplasty between 01/11 and 12/13. Demographic variables, intraoperative parameters, pre- and postoperative echocardiographic studies were analyzed. A total of 108 pts undergoing TVR formed the RR group and 20 the FB group. Patients treated with suture annuloplasty or other devices were excluded.
Age, gender, preop. Euroscore II and severity of tricuspid regurgitation (TR) did not differ among groups. Intraoperative parameters (procedure time, cardiopulmonary bypass and cross-clamp time) were also similar. Long-term mortality with a median follow-up of 1361d (range: 854-1900d) was similar, too. Postoperative echocardiographic follow-up revealed a trend for more severe TR after reconstruction with the band than with the rigid ring (p = .064, Mann-Whitney-U). Subgroup analysis of patients undergoing mitral valve plus concomitant tricuspid valve reconstruction demonstrated more moderate TR in the FB group (Table 1).
Tricuspid valve reconstruction with the rigid MC3 ring yields a higher rate of just trace tricuspid regurgitation than with a flexible band in patients undergoing concomitant mitral valve surgery. A trend towards more trace tricuspid regurgitation was observed in the overall study cohort. Longer follow-up or even more desirable a multi-center study is warranted to determine if usage of flexible bands will lead to more reoperations or more overt right-sided heart failure than rigid rings.
